VISTAS OF COPPELL, PHASE I, PRELIMINARY PLAT P & Z HEARING DATE: March 21, 1996 C.C. HEARING DATE: April 9, 1996 LOCATION: East side of Denton Tap Road; north of the Denton Creek SIZE OF AREA: 21.78 acres 113 residential lots CURRENT ZONING: PD-SF-7 REQUEST: Approval of preliminary plat for a 113-lot residential subdivision APPLICANT: Owner: Engineer: Vista Properties, Inc. Carter & Burgess, Inc. 5950 Berkshire Lane, Ste. 400 7950 Elmbrook Dr., Ste. 250 Dallas, TX 75225 Dallas, TX 75247 (214) 360-1524 (214) 638-0145 HISTORY: The City of Coppell annexed portions of the Vista Ridge Business Park in 1986 and 1990, including the pwperty currently requested for rezoning. In connection with the annexation proceedings, the City held public hearings to establish the existing zoning and reinforced those decisions by adopting a new Official Zoning Map in 1991 as part of Ordinance 91500, the current Zoning Ordinance. On January 18, 1996, and on February 15, 1996, the Planning and Zoning Commission denied this preliminary plat pending its decision on the companion zoning case. Item # 6 TRANSPORTATION: Denton Tap Road is a P6D, a six-lane divided (120 foot r.o.w.); currently, a two-lane roadway; the S.H. 121 Bypass will be built to freeway standards with access roads in 450 feet of r.o.w. SURROUNDING LAND USE & ZONING: North - vacant; City of Lewisville South- vacant, Denton Creek; 'TC' Town Center Fast - vacant; 'HC' Highway Commercial West - vacant; Planned Development ~PD-133 FP, HC, SF-12, SF-9' COMPREI-IF. NSIVE PLAN: The 1987 Comprehensive Plan shows this property outside the boundaries of the planning area. The proposed 1996 Comprehensive Plan shows the area as suitable for low- density residential development. DISCUSSION: Action on the proposed preliminary plat is dependent upon the outcome of the companion rezoning request and resulting PD site plan. However, the complexity of the issues involved in the zoning case has made it difficult for staff to deal as thoroughly as possible with every final detail of the plat. One such detail, involving woodlands on Tract I, is of considerable importance. Tract I is wooded, but Tracts H and HI are virtuany treeless-except along the drainageway between. They are treeless because the land contains fill dirt which brought it above flood plain. In reviewing the plans for Tract I, staff thought it likely that the entirety of the site would have to be raised similarly and that virtually all its trees would be lost as well. But at the most recent Development Review Committee meeting, staff has learned that this may not be the case. Tract I is wooded mostly with small trees, but also has a significant number of larger species. If homesites do not need to be filled, many of these trees can be saved. To make informed decisions, we need more information than we currently have available. We need to know the proposed finished floor elevations as required by Section VIH, C, paragraph 16g, of the Subdivision Ordinance. We need to know where the 'larger trees are, as required by paragraphs 10 and 1th of the same section. We also need a tree preservation plan as stipulated in paragraph 14. In undertaking to preserve trees, it is important to remember that knowing their location does not necessarily protect them. City ordinances do not protect trees within proposed street right-of-way. Information about their location is useful, nevertheless, and may influence decisions regarding Item # 6 street location. To avoid further delay of the platting process, it would be possible to review this information prior to City Council approval of the preliminary plat. The Planning and Zoning Commission would have the opportunity to see the information upon its review of the final plat. RECOMMENDATION TO THE PLANNING AND ZONING COMMISSION: Staff recommends action consistent with that taken on the companion rezoning request, subject to engineering comments. If that action results in approval of a site plan identical to the street and lot arrangement shown on the proposed preliminary plat, staff recommends approval of the preliminary plat subject to submission of proposed finished floor elevations on each lot, a tree survey, and a tree preservation plan. ALTERNATIVES: 1) Recommend approval of the Preliminary Pht 2) Recommend disapprove of the Preliminary Plat 3) Recommend modification of the Preliminary Plat ATTACHMENTS: 1) Preliminary Plat Phase 1 2) Preliminary Water and Sewer Plan Phase 1 3) Preliminary Drainage Area Map Phase 1 4) Departmental Comments Item # 6 DE VELOPMENT R E VIE W COMMI ENGINEE NG COMMENTS ITEM: Wtstas oJ~ Coppell.
